ALSA: seq: fix passing wrong pointer in function call of compatibility layer
This commit is a fix for Linux 4.9-rc1. In former commit, a function call of compatibility layer for ALSA sequencer core was obsoleted by an alternative. Although, the alternative gets a pointer to kernel stack due to mis-programming. As a result, ALSA sequencer core unexpectedly refers over kernel stack.
